Ignition switch is a solid culprit. the contacts get worn out or even "stretched " due to "Forced" turning of the key. You know the part where you try to turn the key past the stop point.

SOURCE: po452 trouble code changed sensor engine light

you may have to drive it several days for the light to go off, or have the codes cleared. personally I would just drive it. if the computer tests it, and it passes the test, it will go off on its own.

SOURCE: codes po452 and po453

both codes point to the fuel tank evap pressure sensor. High and low input faults.
Try clearing the codes first and seeing if they come back

You may have a vacuum leak, cracked or open vacuum line or faulty sensor.

SOURCE: trouble code shows po452 which is the evap

P0452 Evap.Emission System-Pressure Sensor Low Input

The evaporative emission control system prevents hydrocarbon vapors from escaping from the fuel tank into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Fuel Tank Pressure Sensor (FTPS) is an integral part of the evaporative monitoring system. The PCM monitors the FTPS signal to detect vacuum decay and excess vacuum. The FTPS measures the difference between the air pressure inside the fuel tank and outside air pressure to check the purge control solenoid valve operation and for leak detection in the evaporative emission control system by monitoring pressure and vacuum levels in the fuel tank during the purge control solenoid valve operating cycles.

Failed 2001 chevy blazer code 452


(PO452 general motors code, low evaporative emmisions control input) Believe it or not it could be that the gas cap is not on tight or needs to be replaced. Other than that: vacuum line or evap. canister leak.

Abs light on with a p0452 code


ABS -- is one problem
Possible Wheel Speed Sensor ,but
you can't guess Use codes & other
resouces to diagnose

EVAP System Code PO452 -- may be a
Pressure Sensor issue ,all I have is Low Input
I assume that means high resistance in the solenoid coil,
thus low voltage detected
Again- need scanner & evap smoke machine ,to check out,
unless your guy shot guns common items & gets lucky at
your expense,changing parts

I have a 1998 isuzu hombre. it keeps throwing 3 engine codes. they are as follows po172-system to rich bank #1..2nd code is po405-egr sensor a low cicuit..and 3rd code po452 evap emission system presure...


The lean condition is usually the result of an O2 sensor fault, or a vacuum leak.
The EGR may be stuck and setting that code, you can remove clean and check wiring connections.
The po452 fault code is related to a low input signal from your EVAP system which is to do with your purge canisiter system...You could have a faulty sensor in this system or again bad wiring...

Troubleshoot these areas, clear all fault codes and see how she runs.

Good luck, i hope this helps.
